To all who? it may cor/1mm:

Be it known that I, PAUL Hanson, a citizen of the United States,residing at llild Horse, in the county of Cheyenne and State ofColorado, have invented certain new and useful Improvements inButter-Making Machines, of which the following is a specification.

This invention relates to machines for making butter, and moreparticularly to large machines of this class which are connected. bymeans of a driving pulley to a suitable source of power.

The principal. object, therefore, 01' the invention is to provide amachine of the class described which is easily controlled and operatedand which is effective and ellicient in operation.

For the attainment of these ends and the accomplishment of other new anduseful objects, as will appear, the invention consists in the featuresof novelty in the construction, combination and arrangement of theseveral parts generally shown in the accompanying drawing and describedin the speci lication, but more particularly pointed out in the appendedclaims.

met in churning the cream, and in working the butter after the cream ischurned.

The present invention relates more particularly to the manner oif movingthe drum and the means for operating and controlling the drum and thebutter working rollers.

Referring now more particularly to the drawings, the numeral 1.0 will beemployed to designate generally the entire drum or receptacle. Thisreceptacle may be of any suitable diameter and length, machines ofvarious capacities being pretei'ably constructed by varying the lengthof the receptacle rather than the diameter. To support the receptaclebearing standards '11 and 12 are provided, which are located preferablyadjacent the ends of the receptacle and are connected to each other bymeans of the tubular members it At the rear end of the receptacle 10 ametal band l-t is disposed and mounted in the bearing standards 11 onopposite sides oi. the drum are flanged rollers 15 which are disposed sothat they contact with the metal band let and permit the receptacle tobe rotated upon them. At the other end of the receptacle, which will bereferred to as the forward end, a metal ring 16 is secured to thereceptacle in any desired or suitable manner. This ring formed on oneedge with teeth 17 and on the other edge with a smooth surface 18, whichsubstantially coincides with the pitch line of the gear teeth 17.Mounted in the bearing standard 112 are shafts 19, 19, and mounted uponthe shafts are rotatable driw ing gears 20, 20, having gear teeth 21,and a plain or roller surface 22 substantially coinciding with the pitchline of the gear teeth 21.. This driving gear 20 is adapted to mesh withthe teeth 17 of the metal ring 16, the roller contacting with the rollersurface 18 of the ring to support the receptacle at its forward end.Thus it is seen that the receptacle is suitably mounted for rotation atits ends without lhe necessity for a. central bearing or support or adriving shaft which coincides with the longitudinal axis of thereceptacle, and it will he noted that the driving gears at the forwardend also support the drum, being formed with a bearing surface whichsubstantially coincides with the pitch lines of the gears and engagewith a corresponding surface on the driving ring at the "forward end.Disposed about the gear 20 and the gear teeth 17 is a guard 17 which issecured at one end to the bearing standards 12 and at the other end tothe tubular member 13. This guard is for the purpose of preventing theengagement of the teeth with the clothing of an operator, and to preventother materials or substances from lodging in the gears.

To rotate the drum the shaft '19 is provided at its outer end with adriving pulley 23, freely rotatable on the shaft, and with a collar 24keyed to the shaft. The under sur face of the pulley 23 is provided withan inclined face 25, and a clutching member 26 with a correspondinglyinclined face is movable longitudinally of the shaft and engages thecollar 24 thereof by means of a slot 27. This member is provided with agroove 28 to receive a yoke 29 (see Figs. 1, 2 and 5), which is attachedto an operating lever 30. A suitable bracket 31 is provided forsupporting the outer end the shaft 19, and the tubular members 13 arepreferably extended in a forward direction to sustain a support 31 whichmay be connected to or formed integral with the bracket 31, both beingadapted to support the outer end of the shaft, and the lever 30 beingpivoted to the support 31, as shown, or to the bracket 31. The gear 20is preferably keyed to a sleeve member 32 (see Fig. 5), which isrotatable upon the shaft 19 and forms a bearing support for the shaft inthe bearing standard 12. The gear 20 is also preferably provided with asprocket portion 33, preferably fornied integral therewith, but which ofcourse mav be secured to the gear 20 if so desired. 'lhe sleeve 32 isformed with a projecting portion 34, which is preferably located on theside of the bearing standard 12 opposite to that of the gear 20, so thatwhen the sleeve 32 is in position in the bearing standard 12 and thegear 20 is keyed, it will be held firmly in place against longitudinalmovement. with respect to the hearing standard 12. Keyed to the shaft 19adjacent the extending portion 34 of the sleeve member 32 is a gear anddisposed between the gear and the bracket 31 is a freely rotatablemember 35, which has an externally toothed portion 37 with internalteeth 38 projecting over the gear Secured to the extending portion 34 ofthe sleeve 32 and rotatably mounted thereon are pinions 39, which meshwith the gear and with the internal teeth 38 of the projecting portion37. Formed integral with the member 36 is a tubular portion 40 havin anopening 41 and an inclined beveled cam surface or notch 42 at the outerend thereof. The tubular portion projects in the opposite direction fromthe flanged portion 3?, and is adapted to receive a movable pin 43 (seeFigs. 1 and 2) which may be moved longitudinally into and out ofposition to engage the housings of the pinions 39 or lugs 39 formed onthe side of member 36. This member 36 is also provided about itsperiphery with a plurality of notches 44, which may be engaged to holdthe member 36 in fixed position, as hereinafter described.

The movable pin 43 which is mounted in the tubular portion 40 of themember 36 is provided with an enlarged portion 44, which may be securedthereto or formed integral therewith, and which is formed with acamshaped projection which is adapted to be received in the roundednotch or groove 42 of the tubular portion 40. This enlarged portion 44is provided with arms 45 and which extend substantially at right anglesto each other, and which are adapted to be engaged to rotate the pin 43in the opening all. Vhen the arms 45 or 46 so engaged the enlargedportion of the pin is caused to ride upon the grooved portion of thetubular member 40 to move the pin longitudinally into or out ofengagement with the projection 34 of the sleeve member The outer end ofthe pin is engaged or supported by a spring pressed clip 47. This cliphas a slotted opening to receive the end of the pin, and is securedthrough a perforation at the other end to the member 36, the clip beingbent or offset to provide for the projection of the tubular portion 40'The clip 47 is preferably of resilient material, and in order to providefor further movement of the pin 43 the connection of the clip to themember 36 is made slightly more flexible, as, for example, by means of athreaded pin 48, which extends through the perforation in the end of theclip and a spring 49 mounted upon the pin with a nut 50 to keep it inposition and add the proper tension. T he tension of the spring upon theclip may be varied by moving the nut 50 upon the threaded portion of thebolt 48, whereupon the clip 47 will be pressed firmly against the end ofthe pin 43, tending normally to press it inwardly in the tubular portion40. When the pin 43 is pressed inwardly it is disposed in the path ofmovement of one of the lugs, 39, where upon the member 36 and the sleevemember 32 will be driven positively with the shaft l9, forming a directdriving connection for the gear 20 with the shaft 19, so that the gearwill be driven at the speed of the shaft and in the same direction. Thisgearing is of the type commonly known as planetary gearing, and in orderto effect a slow speed movement of the driving gear 20 in the forwarddirection, it is necessary only to withdraw the pin 43 from itsengagement with the lugs 39 and to lock the member 36 against rotationwith respect to the shaft 1. A simple means of accomplishing this resultwill now be described.

A lever 51 is provided with a laterally extending pin 52, which isadapted to engage either one of the arms 45 or 46 when the lever ismoved about its point of pivotal support. In the present embodiment ofthe invention this lever 51 is pivotally mounted by means of lugs 52(see Fig. 5) on the bracket 31. Secured to or formed integral With thelever 51 is a dog 53, which is adapted to engage in the notches 1 1- inthe periphery of the member 36. A spring 51 is also provided, which issecured in any suitable manner to the bracket 31, and which pressesagainst the lever 51 or against the dog 53, tending to press the latterdownwardly into engagement with one of the notches 14. It will beevident that when the planetary gearing is being driven at the samespeed as the shaft 19, the pin 43 must first be retracted from itsposition in the tubular portion 10, and for this purpose the arms 16 aremade of sufficient length to be engaged by the pin 52 of the lever 51before the dog 53 engages in one of the notches 1 1. As soon as one ofthe arms 15 or 46 is so engaged the pin will be retracted by reason ofthe cam-surface of the portion 1-0, and the corresponding beveledportion of the enlargement 14. WVhen the dog 53 is disengaged from itsconnection with one of the notches 1 1 by moving the lever 51 upwardly,one of the arms 45 or 46 will be engaged by the pin 52 to return the pin1-3 to its engaging position in connection with the planetary gearing.

In order to hold the lever 51 and the dog releasably in position, theyare preferably provided or formed with a cam 53, (see Figs. 1 and havingsurfaces disposed at an angle to each other, so that the spring willpress against one of the surfaces to hold the dog and lever in engagingposition, and against the other surface to hold the dog and lover out ofengaging position. An abutment 54; is also formed adjacent the pivotedportion which is disposed to engage the bracket 31 to prevent the lever51 from being turned over too far. It will be evident that the lever isreleasably held in either position by the tension of the spring againstthe cam 53.

From this description it is evident that the receptacle 15 may be drivenin one direction at either high or low speed without varying the speedof the driving pulley, it being necessary only to move the lever 30 toengage or disengage the clutching member from the driving pulley,whereupon the shaft 19 will be rotated and to position the lever 51 toeffect the different changes in speed through the gearing abovedescribed.

In machines of this class it is customary to provide butter workingshelves 55, and one or more butter working rollers 56. If the machine isa large one, it is preferable to em ploy two or more butter workingrollers and the same number of cradles or shelves 55. These shelves maybe arranged in any desired orsuitable position with respect to therollers 56, and in the present exemplification of the invention theshelves are disposed substantially at right angles to the plane of theaxes of the rollers and at the side thereof, so that as the receptacle15 is rotated the material will be lifted by the shelves and directedagainst the rollers.

The shelves are preferably formed of separate slats which may beseparately inserted and removed. Brackets 55 are secured to the ends ofthe receptacle in any desired manner and the separate slats or stripsare each secured to the brackets in any de sired or suitable manner, asfor example, by means of screws.

The rollers are preferably rotated in a reverse direction to thedirection of posi tion of the receptacle itself, so that the materialcarried by the shelves will be directed against the rollers and moved bythe latter against the shelves. In order to mount the rollers within thereceptacle, and to provide for their rotation in the opposite direction,they are provided at the operating end of the receptacle with a plate 57which is preferably provided with a rectangular or slotted opening 58 inthe center thereof. Secured to the receptacle on the outside and at theforward end thereof is a spider 59, to which is secured a shaft (30. Thespider is formed with extending arms which are provided with the tubularportions (31 extending through the end of the receptacle and formed onthe inside with a beveled 0 inner surface (32 (see Fig. Disposed in thetubular portions (51, are shafts (33 which are provided with shoulders(3 1 corresponding with the beveled surfaces (32, and each having arectiuigular head adapted to fit the opening in the plates 57. Mountedon the projecting ends of the shafts (33 are gears 65, and mounted uponthe shaft (50 is an internally geared member 66, which meshes with thegears (55. Also disposed upon the shaft 60 and preferably outside of themen'iber (36 is a sprocket wheel (57. Both the sprocket wheel 67 and themember 66 are freely rotatable on the shaft (30, and in order to ell'ectthe rotation of the rollers 56 suitable 0011- nections may be madebetween the members 6 and 67. For this purpose the member (56 is formedwith openings (38 therein, which in case the member (36 is formed withspokes, as shown in the present exemplilication of the drawing (see Fig.1), are disposed in the spokes. A tubular portion 69 is formed inconnection with the sprocket 67, which is adapted to receive a pin 70.The outer end of the tubular portion 69 is formed with an inclinedbeveled surface 71, and, the pin 70 is provided with an arm 72, by meansof which the pin 70 may be rotated. A spring 73 is suitably disposedwithin the tubular portion 69, tending to press the pin inwardly, andthe longitudinal position of the pin is varied by rotating it in thetubular portion, whereupon the arm 72 will engage the outer end of thetubular portion and the beveled surface 72 to move the pin outwardly orinwardly. When the pin 70 engages in one of the openings 68 the sprocket67 is locked in connection with the member 66 and by rotating thesprocket 67 the gears 65 are caused to rotate, thereby rotating therollers 56 in the corresponding direction. In order to efiect therotation of the sprocket 67a sprocket chain 74: connects the drivingsprocket 38 with the sprocket 67, and it will be noted by referring toFig. 1 of the drawing that the rotation of the gears 65 will be in thedirection opposite to that of the rotation of the receptacle itself. Itis obvious that the butter working rollers 56 may or may not be rotatedwithout interfering with the operation of the receptacle itself. At theother end of the rollers 56 they are pref erably provided with a bearingsupport similar to that shown in cross section in Fig. 6. The end of theroller is recessed adjacent the center and provided with a block 75, ofany suitable material, which is perforated at the center of the rollerto receive the end of a bearing pin 76. A metallic member 77 ispreferably disposed at the bottom of the opening in the block 75, andextends into the roller itself, the top forining a bearingplate for theend of the bearing pin 7 6. This bearing pin 7 6 is preferably enlargedand threaded at 78 and provided with a head '79 and nut at the outerend. Secured to the end of the receptacle 15 is a threaded plate 80, inwhich the pin 76 is adjustable, the threaded portion 78 being adapted tofit the threads in the plate 80. By rotating the bearing pin 76 theroller 56 may be pressed longitudinally in the receptacle, and leakageprevented. at both ends of the receptacle.

The opening by means of which material is inserted or removed from thereceptacle, may extend the full length thereof if desired, butpreferably extends only partof the way and comprises a flat openingformed by omitting a segment from a por tion of the receptacle. Sills 81extend longitudinally of the receptacle and are supported by crosspieces 82. These cross pieces extend across the door opening and thesills 81 are disposed above the cross pieces, so that a flat door 83 maybe positioned above the sills 81, and may be suitably held in po sitionby the clamping devices 84:. It is obvious that in receptacles ofconsiderable length the hoops which extend and hold the receptacle inshape must also pass across the door opening, and for this purpose thecross pieces 82 preferably disposed substantially in line with hoops 86,which are adapted to hold the receptacle in shape, so

that the hoops may be disposed on top of the cross pieces 82, and belowthe top of the SlllS 81. The door 83 is preferably provided with packing87 (see Fig. l), disposed about the edge and extending therefrom,composed of any suitable resilient material, such as cork or the like,which is adapted to tightly inclose the door opening when the door 83 ispressed in closed position.

In order to provide for the expansion and contraction of the receptacle,it is necessary to provide an adjustment, not only for the sides of thereceptacle, but also for the ends, and particularly is this true ofreceptacles of considerable size, for the reason that a little variationof each piece of which the receptacle is constructed will result in alarge variation of them all taken together. For this purpose one or bothends of the receptacle may be formed as shown in Figs. 2 and 8, in whichit will be seen that one of the end pieces 88 is provided with a metalstrip 89 having threaded openings therein to receive the bolt 90. Theadjacent end piece 91, which is thicker than the end piece 88, isprovided with a portion 92 which extends back of the end piece 88 and inclose contact therewith to prevent leakage. A metal strip 93 is disposedbetween the heads of the bolts 90 and the end piece 91 and held in placeby screwing the bolts out vardly in the strips 89, thereby pressing theend piece 91 away from the end piece 88 between the end members of thereceptacle. In a similar manner plates 94 and 95 are disposed betweenadjacent side members of the receptacle separated by the head of athreaded bolt 96, which is threaded through a suitable opening in one ofthe strips. By turning the bolts 96 the adjacent side members may bepressed apart, thereby tightening the side members on the receptacle.Means is also provided for tightening the hoops 86 of the receptacle tohold the receptacle in shape.

A detailed description of the operation of the machine is believedunnecessary, as the operation of the mechanism has already beendescribed. The levers 30 and 51 are employed to control the operation ofthe clutch and the gearing by means of which the mechanism may beconnected to the driving pulley 23, and the gearing position for high orlow speed, as desired. hen it is desired to rotate the butter workingrollers 56 within the drum in a direction opposite to the rotation ofthe drum itself, the pin 70 is moved into engagement with the gearmember 66, whereupon the gear 65 will be rotated in the directionopposite to the rota tion of the drum.

It will be noticed that both of the butter working rollers are rotatedin the same direction. when connection is made with the sprocket 67, andthis direction of rotation is opposite to that of the rotation of thereceptacle itself. These rollers being located at the inner edge of theshelves as they retate, cause the butter to be worked against andbetween the shelves and the rollers, thus efficiently working thebutter.
